COMBINATION SLIDE DEVICE.

Application tiled October 26, 1922. Serial No. 597,211.

To all whom'z't may concern:

Be it knownthat IQTHOMAS PAUL, a subject ofthe'King Vof Great Britain, and a resident of Trail, British. Columbia, Dol minion 'of Canada, .have inventedv certain new andv useful .Improvements in Combination SlideV Devices, Yof which-the 'following is a specification.

. This inventionk relates to a; combination l0 slide for. diagrammatically producing 'group lconnections for polyphase; armature windings .of alternating currentpmotors or generators.

The object oftheinventionpis to produce 15 ail device *as` above characterized which may be usedv by: instructors, :dit'aftsmen,` *or Varmature winders for' graphically i depict-ing group connections` ofj'polyphase armature windings for alternating currentmotors or generators in a clear and 'accurate manner. It is.. also an -object oftliefinvention that vthe slide.. de`vice,`-"beY exceedingly simple in Vconstruction 'and' inexpensive" to.. manufacture.

*Other objects will' hereinafter appear.

.In carryingv out lthe 'invention it isfcontemplat'edy 'to employ basetand three sets of slide'stherefon fonexset. of" slides lindicating the leads ofan.armaturevvindingwhich establish the 'different 1 electrical circuits Atherein, the Asecond set. ofsli'desI indicating 'connectorsffor 'coilj groupspof' anY armature winding,and.the third set of slidesin'dicatingdifferentn groups ,of'coils for armature windings. 'Y

Theinvention is illustrated by Way ofeX- ample in 'theaccompanying' drajwings, .in

f Figure 'similar' ,viewj` graphically longitudinal'edge of said'channelifor av purpose Whichwill later become apparent.

Upon each side oflthe'channel lltheretis provided av groove 13,. eachgroove having itsfside wall provided'withl a laterally extending groove or offset 14 -toform guide- Ways for vthe slides; -positionedi in `these grooves.

-The lead slides-and the group coil connectorslides shown in Figures 4, 4a, 5f, 6, 6, 7, 8, 9, rv19 'and 2O 4are ofY uniform construeh Ition. Flach slide consists in a. substantially square plate 15' with the'v exception of the slides rshown vinV VFigures 84 and 9 in which case the rplate is of rectangularshape. The plate 15 is preferably made of celluloid,;and attached'tojthe lower face of v`said plate is a. runner' 16 compris-ing a lsubstantially "rectangular shaped'boldy member as shown in Figure 3 'having'. an extension* '17' formed upon eacli'side thereof. "The body'mernber ofthe runner 16.1in. each instance is adapted to movewithin either" ofthe slotsl of 'thebase member 10 andtheentensions 17 are adapted to move yin the associated groovesv 14 of said slots and thereby rigidly hold 'the `slidein position` for movement longitudinallyy ofthe.` base 'member y10.

;Each-.of the slides' shown'l Lin'l Figures 10A to' llincl'usive and also `VtheV slide A' .shown in'Figures- 19 a-nd"20 are preferably made' of a thin ceiluloidsheeting. y

As shown to. advantage in'"`Fi'gurel 1 along each longitudinal edge'and. upon the' top lface of the base'y member 10'vtherev are' arranged the numeralsl to '12 inclusive', which arev forther purpose ofindicating. thepoles of` anarmature. lIt will be'ob'served 'that these. rows Iof'numbers read consecutively and in the same direction. .Also' these numbers are so arranged that similar numbers of each row will occur Ydirectly opposite each other. Y

' form one pole and it there were twelve poles there'would'be thirty-six groups ot coils. 'For illustrating this matter there are arranged on each side oit the channel 11 the numeralsA 1 to 36 inclusive as shown. rlhese numerals may be referred to as the group numbers. I Y

In order tov give the pupil or user ot the presentdevice further information relative to armatures for alternating current motors or generators, numeralsare placed upon tlie base tok indicate the. revolutions per -min-Y ute of an armature for producing eitherl60` cycles of cycles current with a given l number of poles.

In Figures4, and 5 the lead slides V"graphically show the lead connections tor either sta-r' orA delta windings. The slides Y shown in .Figures 4 and 4a are companions,

`lio

that is, lthesetwo slides may be lplaced in separate grooves 13 and at the same end of Vthelo-ase 10. Y On each slide there are shown two sets of full lines 18 and 2O which extend parallelto o-ne side of the plate 15 andY occur along tlieinner edge of each slide. The

\ lilies-v 18 represent the neutral leads `ot the windings and each terminates at its inner end in a star, said stars being connected by adashed line 19. .The lines 2O represent- Vthe main leads and are designated by the reference characters L", L and L. 4It

' will be noted that in'Figure 4; Lf occurs intermediate L". and Lm', while inFigure 4a the reference characters L,.LV and L are arranged in consecutive order beginning at the left of the slide. This'illustrates the possible` relationY of .the leads. Also these slides may have otherindicia thereon as at 22 whereby to indicate the deltaI leads of the armature. The; leads L', Lf and L are differently arranged, and each letter has associatedV therewith the two lines20, and between the two lines there occurs the conventional YsignV 22 for indicating delta winding. Figure 5 is substantially the same as Figure 4a but with slight change of Vreference matter thereon.

Figures 6 and 6a show top plan views of Vslides used for connectingY coil groups.

These two Vslides are substantially the saine but whenemployed should be arranged in vdifferent grooves 13. Each plate 15 is provided with six full lines 23 and three broken lines 24. The `broken lines connect with the full lines andthe purpose of these lines is to show the connection between coil ns1/easel k groups of an armature winding. In Figures S and 9 the plate 15 in each instance is provided with three full lines 23, and each full line having extended therefrom at right Vangles thereto` a broken line 24';v The slide in Figure 7 is similar to slide 6a with the exception of a slight change in the connection of lines. Y Y

The slides for graphically showing the coil groups of an armature and which may be referred to as the group slides may consist in any number desired, depending upon the number of different circuits and a arrangements of armature coilsit is desired to illustrate. Each of the slides employe-d Y should be made oa thin sheet of celluloi-d or a light material which agrees in length with the base 10 of the device and which is ot such -a width that the same will freely slide within the channel 11 in said base.v .A form of group slide is shown in Figures 19 and 20, and this slide is generally indicated by the reference characterA. Other forms of group slides are shown in Figures 10 to A 18 inclusive .and indicated by the reference characters B, 0,11), F, G, H, LJ, I( respec-V tively. Each full line 25 shown uponthe slides represents a group of coils, and each dashed line 26 represents a connectonfor said groups of coils..l v

It should be here stated that the lead slide shown in .Figure 19V may at all times be positioned in the guideway or groove 13 at the end representing the beginning Vof theY l Vhave been used to connect a one circuit, two

pole armature. -In Figure 2O slides'of the form shown in Figure 19 lill the groove 13 upon one side of the Vgroup slide A, while companion lead slides lill the same groove on the other side of the group slide A. This represents a parallel connection for armature leads and indicates or illustrates an armature with a large number of poles'.

The form of coil group slide shown in Figure 10 and designated by the reference character B mightbe employed for three or six circuits and twelve poles, thatris with the proper lead slides and connector slides the winding of such armatures would be diagrammatically shown. The t'orm` of slide C shown in Figure 11 might be employed for showing two circuits and six poles, while the form otslide D in Figure 12 would answer for showing an armature of two circuits and eight poles. The form of slide F, Figure 13 mayillustrate an armature with two circuits and twelve poles;

the form of slide`G,rFigure.14, may illus-A trate a four circuit armature with twelve poles; the form of slide H, Figure 15,.may

Abe .used for illustrating an armature with poles; the slide J, Figure 17, two or four circuits and twelve poles, and the slide K, Figure 18, three or six circuits and twelve poles. The different lead slides may also be manipulated to indicate either star or delta connection of the armature, and also the diiferent slides permit illust-rating whether or not the armature coils are connected in series or parallel.
